STOPPER FOR VESSELS.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed April 19,1906. Serial No. 312,715.

To all whom it may concern:

Be it known that I, ABBor AUoUs'rUs'Low, a citizen of the United States,residing at Horseshoe, St. Lawrence county, New York State, haveinvented certain new and useful Improvements'in Stoppers for Vessels,

of which the following is a specification.

My invention relates to means for sealing vessels and it consists incertain elements fully set out in the following specification andclaims.

In order that those skilled in the art to which my invention relates mayunderstand, construct and use my invention I will proceed to describe itreferring to the drawings herewith forming part of this specification.

Figure 1. is a central longitudinal section of a bottle with the sealingcap posed above it previous to its being closed down upon the washer andstopper in the bottle mouth. Fig. 2. is-a'similar view showing thesealing cap closed down upon the washer and stopper in the bottle mouth.Fig. 3. is a similar View showing the sealing cap being removed from thebottle to open it, with the sealing material drawn out of the bottlemouth by the cap and its surrounding washer. Fig. 4. shows a centrallongitudinal section of a sealing cap and washer as in Fig. 1. butshowing the stopper with a straight part above and a taper at bottom,the washer surrounding the straight part thereof.

A. is the body of the bottle and B is its neck.

0. is the usual bead surrounding the bottle neck near its top.

D. is the top surface of the sealing cap. E. is a flange pendent fromsaid top surface D.

F. is a raised portion of the top surface D, centrally thereof.

G. is a stopper tapered at its lower end.

H. is a thick washer surrounding the stopper G.

I. is a cap lifter or remover.

J. is the taper bore of the bottle mouth.

The washer H, and stopper G, are placed in the bottle as shown atFig. 1. the washer H will then nearly extend to the depth of the capflange E, when the cap is forced over sealing material in the bottle tosecure it ,on the bottle, the washer H is compressed upon the top of thewalls of the bottle mouth, as seen at Fig. 2, thus the washer H iscaused to grip the stopper G firmly, circumferentially, and when asshown at Fig. 3, the cap is removed from the bottle the grip of thewasher on the stopper causes it to pull the stopper out of the bore ofthe bottle. It is necessary that the washer should be of good thicknessin order to have body enough to get a strong grip on the stopper, sothat the combined grip of the cap and washer may pull the stopper out.

Having now fully described my invention and the manner in which I haveembodied it what I claim as my invention and desire to secure by LettersPatent is In a sealing means for vessels the combination consisting of ametal cap having a top surface; a circumferential flange pendent fromsaid top surface and a raised portion centrally of said top surface; awasher covered by said metal cap; a plug stopper contained within saidwasher, all combined to operate when secured to a vessel by means of thependent flange, to enter the said stopper in the bore of the vessel andto compress said washer tightly around the body of said stopper, wherebya sealing of the cap upon the vessel, is primarily by the plug stopper,secondarily by said washer, and thirdly by the contact of the saidpendent flange with the vessel neck in securing it to the vessel, andwhen the cap is removed from the vessel the said stopper is withdrawn bymeans of the grip of the said washer upon it and the said pendent flangeand raised cap substantially as specified.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses, this seventh day of April 1906.

ABBOT AUGUSTUS LOW.
